Objective:
We compared the effect of computerized-assisted cognitive rehabilitation (CACR) and conventional rehabilitation (CR) on visuospatial perception, visual field and attention, and visual memory in patients with unilateral spatial neglect.
Methods:
Forty five patients with unilateral spatial neglect from brain injury were randomized into the experimental group (n = 22) or the control group (n = 23). The experimental group received CACR intervention, including saccadic eye movement, visual field, and visual-motor coordination training, whereas the control group received CR with 30 minutes for each intervention, five times a week for 4 weeks. Outcome measures were Motor-Free Visual Perception Test (MVPT) and Line Bisection Test (LBT) for visuospatial perception, Visual Span Test (VST) for visual field and attention, and Visual Recognition Test (VRT) for visual memory, evaluated before and after each of intervention
Results:
A statistically significant difference was found in MVPT, LBT, VST, and VRT between the groups after adjusting for baseline values. Furthermore, the effect sizes showed a large effect on the VRT, a moderate effect on the LBT and VST, and a small effect on the MVPT in favor of the CACR.
Conclusion:
The CACR may be an effective intervention to treat the unilateral spatial neglect.
